SoftS (Soft Start, Auto Restart & Frequency
Jittering Control)
The SoftS pin combines the function of Soft Start
during Start Up and error detection for Auto Restart
Mode. These functions are implemented and can be
adjusted by means of an external capacitor at SoftS to
ground. This capacitor also provides an adjustable
blanking window for high load jumps, before the IC
enters into Auto Restart Mode. Furthermore this pin is
also used to control the period of frequency jittering
during normal load.
FB (Feedback)
The information about the regulation is provided by the
FB Pin to the internal Protection Unit and to the internal
PWM-Comparator to control the duty cycle. The FB-
Signal controls in case of light load the Active Burst
Mode of the controller.

CS (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated Depl. CoolMOS™. If CS reaches the internal
threshold of the Current Limit Comparator, the Driver
output is immediately switched off. Furthermore the
current information is provided for the PWM-
Comparator to realize the Current Mode.

Current Limiting is now possible in a very accurate way.
E.g. Ipeak = 0.5A with RSense = 2. Without Propagation
Delay Compensation the current sense threshold is set
to a static voltage level Vcsth=1V. A current ramp of
dI/dt = 0.4A/µs, that means dVSense/dt = 0.8V/µs, and a
propagation delay time of i.e. tPropagation Delay =180ns
leads then to an Ipeak overshoot of 14.4%. By means of
propagation delay compensation the overshoot is only
about 2% (see Figure 11).

Figure 11 Overcurrent Shutdown
The Propagation Delay Compensation is realized by
means of a dynamic threshold voltage Vcsth (see Figure
12). In case of a steeper slope the switch off of the
driver is earlier to compensate the delay.

3.6 Control Unit
The Control Unit contains the functions for Active Burst
Mode and Auto Restart Mode. The Active Burst Mode
and the Auto Restart Mode are combined with an
Adjustable Blanking Window which is depending on the
external Soft Start capacitor. By means of this
Adjustable Blanking Window, the IC avoids entering
into these two modes accidentally. Furthermore it also
provides a certain time whereby the overload detection
is delayed. This delay is useful for applications which
normally works with a low current and occasionally
require a short duration of high current.

VSoftS swings between 3.2V and 3.6V after the SMPS is
settled and S2 is on while S3 is off, this is due to the
frequency jittering function that is making use of the
Soft Start pin. If overload occurs VFB is exceeding 4.5V.
Auto Restart Mode can’t be entered as the gate G5 is
